\ sHu'r'rLE-Box MOTION FOR Looms.

Application med August 27, 1925, Serial No. 52,757,`and in FranceDecember 5, 1924.`

This invention relates to shuttle box motions ot looms of the `kind inwhich toothed sectors carried by a rotatably mounted plate or disc areadapted to engage with freely rotatable satellite pinions, whereby eachpinion is periodically given a-lialf rotation at each passage ot' atoothed sector in engagement therewith, the pinions being adapted to berespectively clutched, under the control of the card `mechanism of theloom, to corresponding rotatable members mounted upon the same axes asthe satellite pinions Vand provided with `cranks or crank pins by which`movement of the rotatable membersis communicated to the shuttle boxesthrough levermechanism, one halt rotation of the respective pinions servin to effect `the rise of the shuttle boxes, w rile the succeedinghalfrotation serves to effect the fall of the boxes. By suitable Operationot the clutches by which the satel. lite pinions are connected to therespective rotatable members, any desired position f` of the shuttleboxes may be obtained.

The invention specially relates to shuttle box looms ot the kindreferred to, such as described; inthe speciication ot the copendingapplication No. 16,459 dated 18th March, 1925, Patent No. 1,617,143, andin which four satellite pinions disposed t-wo and two in differentplanes areemployed,`

whereby any desired position lot the shuttle boxes from one to twelve,may be obtained, the rotatable members being connected to the shuttleboxes by means ot lever and rack and pinion mechanism so arranged that ahalf rotation of each ot two ot the satellite pinions'causes theshuttleboxes to rise or Atall to an extent of four boxes, while thethird and fourth satellite pinions cause the rise or fall of the boxestoan extent of two boxes and one box respectively.

In such mechanism each satellite pinion isf clutched to the respectiverotatable member by means of a pin mounted within a hole in therotatablemember or a part integrally secured thereto, which pin isadapted alternatively ltoengage within one oftwo diametrically disposedholes inthe satellite pinion, the pin being pressed into the respectivehole by means "of an Operating member Aunder the control of the cardmechfV anistn. y y

VThe present invention 4has among its objects to provide an improvedconstruction of the mechanism by which the clutching `spindle or shaft bby means o of the satellite pinions to the respective rotatable membersis effected. A

According to the present invention in shuttle boxmotions of the kindreferred to the means' by which each satellite pinion 1s alternativelyclutched under the contro] ofthe card mechanism of the loom to therespective rotatable member, comprises a pin mounted` to revolve withand about the axis of the rotatable member, and adapted to engagealternatively with one of two corresponding diametrically disposed holesin the satellite pinion, a pair of independentV operating membersdisposed laterally of the axis of the satellite pinion in determinedpositions, such that `they may operate to press the pin into one of thetwo diametrically disposed holes in the satellite pinion, whereby-oneoperating member serves to cffect the rise of the shuttle boxes and theother to effect the fall of the schuttle boxes, and-means connectingeach of the said op` erat-ing members to the card mechanism of the loom.

The invention is hereinafter described by way of example with referenceto the accompanying diagrammatic drawing, in which: y

Fig. 1 is a front sectional elevation on the line E-F Figurel 2 showingone of the four satellite pinions.

1Fig.`2 is a horizontal section on the line Av-B, Figure l. i i

Fig. 3 is a sectional side elevation on the line C-f-D Figure 2, and

Fig. 4 is a rear view corresponding to Figure 1. I

The pinion o is provided `freely rotatable and withv `two tdiametrically disposed lholes c c1 in which holes a pin (l carried in apart f, keyed or otherwise integrally secured to a sleeve or member nrotatably mounted upon the spindle or'shatt ,`may alternatively beAengaged."` The pin (l is provided with a re* turn spring c mountedwithin `a recess provided lor the purpose within the `part f.

The parts f, g and/1, `lorm kan integral uniti `which rotatable upon thespindle or shaft b and is maintained in fposition on the the ring gandthe disc h and at its `forward [extremity by the [lange m ontbegspindle.0r shaft` engaging within corresponding recesses inthe sleeve or membern. The sleeveor member a lsatits outer extremity providedfwth alaterally extending flange or part nl upon fai ico

-and the part j".

the face et which a crank n2 or the equivalent, by which motion istransmitted t'o the shuttle boxes, isniounled. The pinion (i isrotatably mounted upon the sleeve and .is disposed between the laterallyextending tlange or part nl ot the sleeve or member n The pinion o isrot-ated intermittently, but always in the same direction and throughhalt a revolution on each movement. lt will be understood that, the cank 'a2 being disposethtor example, in the uppermost position, the pincl is disposed, for example, at 90o to one side. lt' the pinv be engagedwith the pinion i in one ot' the holes c, c1, the pinion will carry thecrank n2 into the lowermost position thus raising the shuttlc boxes orvice versa. The pin (Z will now be d. Jposed inthe opposite lateralposition tarding eliect on the rotatable and when it is next engagedwith the pinion c', the latter will carry the crank fr again to theuppermost position thus lowering the shuttle bof; or vice versa.

llwo cpc i ing arms fz', y' are pivotally mounted upon the spindle lr,and are integrally provided with the respective arms il, jl respectivelyJiorming bell crank levers, and the respective arms 1, il are eachconnected at their ends to flexible men'ibers or cables Z actuated bythe card mechanism ot the loom.

TWhen for example the upward movement thus clutched to the rotatablesleeve or mcmber it.

A spring pressed pin a: nnmnted within a recess in a stationary part ofthe mechanism is adapted to press against the rear 'tace ot the disc 7Land thus to exercise a slight resleeve or member n. By such means whilethe pinion is being' rotated the pin (Z engaging within the hole c1 inthe pinion a is subjected to a slight shearing action suliieicnt tomaintain it within the hole c1 until the rotation ot the pinion ceaseswhereupon the pin (l is withdrawn trom the hole c1 by means ot' thespring e. By such means the half rotation ot the pinion is transmittedto the rotatable sleeve or member n and the shuttle boxes are caused temove into the desired position.

Then the fall of the boxes is to be elected, the operating arm 1 havingbeen allowed to return to the inoperative position so that the pinion cturns freely, the arm jis actuated by the respective lexible member orcable Z to torce the pin Z again into the hole c1 in the pinion acausing the descent ot the boxes.
